Unpredictable growth pattern of costochondral graft

Bahman Guyuron; Carlos I. Lasa

Costochondral grafts have gained increasing popularity in reconstruction of the temporomandibular joint and condyle in children. This is a report on the long-term follow-up of eight adolescent patients who underwent reconstruction of the temporomandibular joint and ramus for correction of hemifacial microsomia or trauma-related temporomandibular joint ankylosis during varying periods of growth. Six patients had hemifacial microsomia, and two suffered from posttraumatic temporomandibular joint ankylosis. Average follow-up was 80.4 months. Four patients had excessive growth of the graft, one patient had suboptimal growth, and three patients had no growth. In addition, one patient had undergone four procedures for significant graft overgrowth. Based on this study and review of the literature, we have concluded that the growth pattern of the costochondral graft is extremely unpredictable, ankylosis is a common problem following a temporomandibular joint reconstruction with costochondral graft, and mandibular overgrowth on the grafted site can actually be more troublesome than the lack of growth. Furthermore, maxillary growth is proportionately influenced by vertical mandibular growth of the graft, while the horizontal maxillary growth is not altered. Ankylosis is a result of ossification of the cartilaginous portion and the three-dimensional graft overgrowth, aggressively extending beyond the cartilage graft boundary. Based on this study, we recommend that this procedure be performed only on severe deficiencies. Adequate amounts of soft tissue should be retained between the skull base and the graft, and we further recommend harvesting the graft from the fourth or fifth rib, which may reduce the potential for overgrowth.(ABSTRACT TRUNCATED AT 250 WORDS)

Background: Many of the nearly 30 million Americans suffering with migraine headaches are not helped by standard therapies, a proportion of which can harbor undesirable side effects. The present study demonstrates the efficacy of independent surgical deactivation of three common migraine headache trigger sites through a double-blind, sham surgery, controlled clinical trial. Methods: Seventy-five patients with moderate to severe migraine headache who met International Classification of Headache Disorders II criteria were studied. Trigger sites were identified (frontal, temporal, and occipital), and patients were randomly assigned to receive either actual or sham surgery in their predominant trigger site. Patients completed the Migraine Disability Assessment, Migraine-Specific Quality of Life, and Medical Outcomes Study 36-Item Short Form Health Survey health questionnaires before treatment and at 1-year follow-up. Results: Of the total group of 75 patients, 15 of 26 in the sham surgery group (57.7 percent) and 41 of 49 in the actual surgery group (83.7 percent) experienced at least 50 percent reduction in migraine headache (p < 0.05). Furthermore, 28 of 49 patients in the actual surgery group (57.1 percent) reported complete elimination of migraine headache, compared with only one of 26 patients in the sham surgery group (3.8 percent) (p < 0.001). Compared with the control group, the actual surgery group demonstrated statistically significant improvements in all validated migraine headache measurements at 1 year. These improvements were not dependent on the trigger site. The most common surgical complication was slight hollowing of the temple in the group with temporal migraine headache. Conclusion: This study confirms that surgical deactivation of peripheral migraine headache trigger sites is an effective alternative treatment for patients who suffer from frequent moderate to severe migraine headaches that are difficult to manage with standard protocols.

Aesthetic indications for botulinum toxin injection

Bahman Guyuron; Sam W. Huddleston

A clinical trial was undertaken to evaluate the effects of commercially available botulinum toxin on 14 hyperactive corrugator muscles, 14 procerus muscles, one case of congenital aplasia of the depressor labii inferioris muscle, and one case of iatrogenic injury to the ramus mandibularis branch of the facial nerve with paralysis of the depressor labii and mentalis muscles. Of the 31 muscles injected, 28 were appropriately paralyzed with the initial injection. The desired results were obtained in the 3 remaining muscles following a second injection. The ability to frown was nullified in all subjects, resulting in the elimination of glabellar lines. Facial symmetry was achieved in both patients with muscle imbalance. The average duration of the paralysis was 8 weeks, with a range of 2 to 16 weeks. However, this period was prolonged in the latter part of the study with an adjustment of the toxin dose.Our results demonstrate that botulinum toxin injected into overactive facial muscles does produce a predictable and reversible paralysis and eliminates or ameliorates deep frown lines. We also illustrate its use in achieving facial symmetry in one patient with congenitally absent depressor labii inferioris and platysma muscles and in another with postrhytidectomy facial nerve paralysis.

Comprehensive surgical treatment of migraine headaches.

Bahman Guyuron; Jennifer S. Kriegler; Janine Davis; Saeid B. Amini

The purpose of this study was to investigate the efficacy of surgical deactivation of migraine headache trigger sites. Of 125 patients diagnosed with migraine headaches, 100 were randomly assigned to the treatment group and 25 served as controls, with 4:1 allocation. Patients in the treatment group were injected with botulinum toxin A for identification of trigger sites. Eighty-nine patients who noted improvement in their migraine headaches for 4 weeks underwent surgery. Eighty-two of the 89 patients (92 percent) in the treatment group who completed the study demonstrated at least 50 percent reduction in migraine headache frequency, duration, or intensity compared with the baseline data; 31 (35 percent) reported elimination and 51 (57 percent) experienced improvement over a mean follow-up period of 396 days. In comparison, three of 19 control patients (15.8 percent) recorded reduction in migraine headaches during the 1-year follow-up (p < 0.001), and no patients observed elimination. All variables for the treatment group improved significantly when compared with the baseline data and the control group, including the Migraine-Specific Questionnaire, the Migraine Disability Assessment score, and the Short Form-36 Health Survey. The mean annualized cost of migraine care for the treatment group (

5530) (p < 0.001). The mean monthly number of days lost from work for the treatment group (1.2) was reduced significantly compared with the baseline data (4.41) and the control group (4.4) (p = 0.003). The common adverse effects related to injection of botulinum toxin A included discomfort at the injection site in 27 patients after 227 injections (12 percent), temple hollowing in 19 of 82 patients (23 percent), neck weakness in 15 of 55 patients (27 percent), and eyelid ptosis in nine patients (10 percent). The common complications of surgical treatment were temporary dryness of the nose in 12 of 62 patients who underwent septum and turbinate surgery (19.4 percent), rhinorrhea in 11 (17.7 percent), intense scalp itching in seven of 80 patients who underwent forehead surgery (8.8 percent), and minor hair loss in five (6.3 percent). Surgical deactivation of migraine trigger sites can eliminate or significantly reduce migraine symptoms. Additional studies are necessary to clarify the mechanism of action and to determine the long-term results.

The anatomy of the greater occipital nerve: Implications for the etiology of migraine headaches

Scott W. Mosser; Bahman Guyuron; Jeffrey E. Janis; Rod J. Rohrich

The senior author (BG) introduced the modern concept of migraine surgery in 2000. Since then, over 40 articles have been published by eight centers across the US, Europe, and Asia, describing positive outcomes after surgery in 68–95% of cases. Surgeons, neurologists, and patients are increasingly interested in this new treatment method. However, the majority of publications on this topic are found in surgical literature, with few articles presented in neurology journals. This review is an introduction to migraine surgery for neurologists from a surgeons view. It discusses the surgical treatment of migraine headaches based on the discoveries made and articles published by the senior author. It outlines the current history of migraine surgery, presents evidence supporting its effectiveness, and tries to dispel claims that what we are seeing is a placebo effect. It further describes detection of trigger sites and outlines surgical techniques of peripheral nerve decompression. We hope that this review will generate a positive discussion between surgeons and neurologists and lead to more interdisciplinary collaboration for the benefit of the patients in the future.

Precision rhinoplasty. Part I: The role of life-size photographs and soft-tissue cephalometric analysis.

Bahman Guyuron

The achievement of consistently superior results in rhinoplasty is rendered difficult in part by a number of complex interplays between the anatomical structures of the nose and the techniques used for their alteration, such as tip sutures. The effects of sutures depend largely on the magnitude of suture tightening, the intrinsic forces on the cartilages, cartilage thickness, and the degree of soft-tissue undermining. The tip complex is perhaps the most intricate of the nasal structures, exhibiting subtle but evident responses to manipulations of the lower lateral cartilages. The three-dimensional effects of nine suture techniques that are frequently used in nasal tip surgical procedures are discussed and illustrated. (1) The medial crura suture approximates the medial crura and strengthens the support of the tip. The suture also has effects that are less conspicuous immediately. There is slight narrowing of the columella, caudal protrusion of the lobule, and minimal caudal rotation of the lateral crura. (2) The middle crura suture approximates the most anterior portion of the medial crura. There is greater strengthening of the tip and some approximation of the domes with this suture. (3) The interdomal suture approximates the domes and can equalize asymmetric domes. However, the entire tip may shift to the short side if there is a significant difference in the heights of the domes because of short lateral and medial crura. (4) Transdomal sutures narrow the domal arch while pulling the lateral crura medially. The net results are increased tip projection, alar rim concavity, and the potential need for an alar rim graft. In addition, depending on suture position, cephalic or caudal rotation of the lateral crura may be observed. (5) The lateral crura suture increases the concavity of the lateral crura, reduces the interdomal distance, and may retract the alar rims. Perhaps the most significant inadvertent results of this suture are caudal rotation of the tip and elongation of the nose. This is important because patients who undergo rhinoplasty would often benefit from cephalic, rather than caudal, rotation of the tip. (6) The medial crura-septal suture not only increases tip projection but also rotates the tip cephalically and retracts the columella. (7) The tip rotation suture shifts the tip cephalad while retracting the columella. (8) The medial crura footplate suture approximates the footplates, narrows the columella base, and improves undesirable nostril shape. (9) The lateral crura convexity control suture alters the degree of convexity of the lateral crura. The nuances of these sutures and their multiplanar effects on the nasal tip are discussed.
